When it comes to size this CMMG® Mk47 is the middle child of the bunch. With a 12.5 barrel it’s the longest configuration in the BANSHEE series offering the right blend between maneuverability and ballistic performance. The Mk47 platform is CMMG’s mid-size AR platform utilizing more robust receivers and components like our PowerBolt Technology without adding unneeded bulkiness. If the magwell on the Mk47s looks ready to take AK-pattern magazines you would be right. Since AK magazines were designed around the 7.62x39mm cartridge we figured if it’s not broke why fix it? – Available in a variety of cerakote finish options the BANSHEE series represents the most innovative AR pistols and SBRs available today. From the stylized receivers and EML handguards every BANSHEE is tailor-made to be the personal defense weapon you can always depend on. With full length M-LOK® slots on both sides and the bottom of the handguard as well as M-LOK between the top picatinny rail sections you’ll always have enough space for those must have accessories. – Platform Mk47 – Caliber 7.62x39mm – Operating System Direct Impingement – Barrel Length 12.5 – Barrel Twist 1:10 – Barrel Contour MT – Barrel Material 4140CM SBN – Barrel Twist 1:10 – Muzzle Device CMMG ZEROED Linear Compensator – Muzzle Thread 5/8 x 24 – Gas Port Location Carbine – Gas Block 0.750 Non-Adjustable – Upper Receiver Billet 7075 T6 Aluminum – Lower Receiver Mk47 Billet 7075 T6 Aluminum – Hand Guard CMMG EML11 M-LOK – Finish Cerakote – Charging Handle CMMG ZEROED Ambi – Pistol Grip CMMG ZEROED Pistol Grip – Buffer Type Carbine Mk47 – Receiver Extension Pistol Tube – Trigger Type ZEROED Drop-In – Trigger Guard Integrated – Safety Selector CMMG ZEROED 60/90 Degree – Magazine Magpul 30rd PMAG – Weight 6.1 lbs – Length 28.7
